I have the whole set up and Meth is coming soon and so far everything has been great. Make sure your connections are tight and just be smart with your car and how you drive it. Good gas, at times adding higher octane of 100 to 103 is a great idea and also alot more fun :-) Good luck and enjoy.

Cracking up. but I believe the n55 starts having hiccups at 20 k with Ke without the jb4. Do regular maintenance. I change my oil every 5000. It's a BMW. It's high maintenance...like girls lol

Why change the oil at every 5K? I'm sure what your doing is a good thing, keeping the oil fresh in the engine is like having good blood in your body. But doesn't BMW know what there doing by having the oil changes at a certain mileage? I'm sure the engineers aren't dumb.....I just do it whenever the car/dealer tell me too....

Well from what i was told, bmw's saving money by pushing the oil changes as late as possible. its not that great for the engine. I rather keep it fresh especially with n55s as they go through more grime. Its free anyways...why not. LOL

The way I look at it, BMW recommends to wait for a long time assuming the car remains stock. The engineers don't expect you to modify the car, as a result, I change it every 5k because I'm boosting 17.5 psi that's just my opinion.

once i get the catless downpipe and jb4 installed im gona have it on map 0 most of the time anyways. its just for the fun once in a blue moon thing. some people take it seriously and want to race every lambo that comes next to them lol.
